GELLAR PIPE;

My present invention relates to re ghting apparatus, and has particularreference to cellar, roof and dock pipe constructions utilized fordirecting fire extinguishing fluid into fluid places where firemencannot enter.

Cellar pipe apparatus usually include a base to which a hose may beattached, and a depending nozzle carrier which is inserted in an openingin a floor or the like, the nozzle carrier supporting one or morenozzles which may be adjusted by ,the fireman outside the room so as toguide the water or other fire extinguishing uid in any desireddirection. These constructions have heretofore had certain operatingdisadvantages, in that it has been difficult to properly support thebase so as to carry the nozzle holder without tilting, and toselectively adjust the nozzles so as to guide the water in the desireddirection; moreover, there has been a lack of balance for the apparatus,due to the reactive effect of the stream emerging from the nozzle.

The objects of my invention are to provide a portable cellar pipeconstruction which is compact, inexpensive to manufacture, and light inweight, and which may be quickly set in operating position and easilycontrolled so as to direct the water streams to any desired point, theapparatus having no reactive effect resulting from the flow of water outof the nozzles.

To this end, my invention consists of a novel arrangement of parts morefully disclosed in the detailed description following, in conjunctionwith the accompanying drawings, and more specically defined in theclaims appended hereto.

In the drawings:

Fig. l is a front elevation showing the novel cellar pipe in operatingposition, a different operating position being shown by means of dottedlines;

Fig. la is a sectional enlarged view through the base and the nozzlecarrier;

Fig, 2 is a View of the nozzle carrier tip and the nozzle, parts beingshown in section;

Fig. 5 is an end elevation of Fig. 1 showing the supporting legs in openposition, parts being broken away;

Fig. 6 is a skeleton view showing the position of the supportingbrackets for carrying the novel 'cellar pipe; and

Figs. 7, 8, and 9 are perspective views of the separate bracket parts.

It has been found advisable to provide a cellar pipe construction whichis light in weight, is inexpensive to manufacture and assemble, which isrigid when in operation, but can be readily manipulated by the operatorso as to direct a stream of water or streams of water in any de- 5 sireddirection, and which has no reaction or side thrust due to the ow ofwater from the nozzle thereof. I have obtained these desirable resultsby constructing a cellar pipe which has lateral supporting legs for thebase, and which has a '10 plurality of nozzles readily shiftable by anoperator so as to direct the outfiowing fluid towards any point, thenozzles being so arranged thatv the reactive effect is balanced.

My improved cellar pipe construction includes l5 the formation of acellar pipe from a plurality of separable parts which are readilyassembled and are fluid tight after assembly, the nozzles being readilymovable to control the flow of water from the cellar pipe. v

Referring ,to the drawings, the novel cellar pipe includes a base I0which has the usual coupling end at one end, and an end nipplearrangement I2 at the other end, two support legs I3, I4, see Fig. 5,being pivotally mounted on the ends v25 of a laterally extending blockI5 cast intermediate the ends of the base Ill, to fold forwardly andtransversely of the base, these legs having calks I6 which contact thefloor to rmly grip the legs when the ends are extended transversely ofthe 30 base III. A cap I'I is rotatably mounted Within the base nippleI2 as indicated in Fig. 1a, suitable packing |8 being provided to make aleak tight joint, the cap I'I threadedly receiving a lock ring 20 whichis screwed down to place the pack- 35 ing I8 under suitable compressionand having spider bars I9 to permit free flow of water into the nozzlecarrier tube 2|. The nozzle carrier tube 2| is secured to the lower endof the cap I1, and has a. carrier yoke 22 xed to the lower 4o endthereof, as by threading. The yoke 22 has two parallel passageways 23,the walls of these passageways being bored to provide two inner centralopenings 24 and two outer openings 25 of larger diameter. A doublenozzle member 28, 45 seeFig. 2, is provided with two oppositely directednozzles, 21, 26 and a central bearing portion 29 which is machined to tsnugly between the inner walls of the yoke 22 and is threaded to receivethe similarly threaded ends of lock rings 30 which 50 have their ends 3|bent over to receive packing rings 32, whereby threading the lock ringson the central bearing 29 engages the packing 32 between the ring ends3| and the inner walls of the yoke;V the inner walls are recessed as at33 -55 to conform to the Shape of the packing rings 32. The lock rings,after tightening, are locked in psition by means of set screws 34 whichpass through oppositely positioned lugs 35 integral with the centralbearing portion 29. The openings 25 are threaded to receive thecorresponding threads of closure caps 36.

Referring to Fig. 1, the cap I1 has spaced bearl collar being rigidlyconnected to a similar collarY 44 positioned below the nipple l2 bymeans of a connecting rod 45a, whereby vertical movement of the collar43 resulting from movement of the handle is imparted to the collar 44. A`connecting barV 45 is hingedly mounted to the collar 44, the lower endbeing connected through a link 46a to lug 46, see Fig. 2, formingintegral.

with or otherwise secured to one of the nozzles,

whereby vertical swinging of the handle 40 produces a correspondingswinging of the nozzle member 26.

Referring now to Figs. 6 to 9, inclusive, the novel cellar pipe isdetachably mounted on a fixed support such as the wall of a building, oron a movable support such as a nre engine, by means of a novel bracketarrangement consisting of three bracket elements 41, 48,49; the bracket41 has a base 50 adapted to be secured to a fixed support and a U shapedtip for receiving the cap I1, a slide cover 52 having a finger portion53 being mounted on the upper face of the bracket so as to selectivelyoverlie the U shaped tip 5l or to be displaced laterally so as to permitremoval of the cap l1 therefrom. The bracket 48 has a base 54 shaped tobe secured to a fixed support, and a bearing plate 55 which has anupstanding top 56 of smaller diameter adapted to be seated in the openend 0f the hose connection H, and the bracket 49l has a base 51 adaptedto be secured to a startionary support, and is provided with a bearingplate 58 which has two spaced recesses 59 for receiving nubs 60positioned at the ends of the nipple yoke 22.

Considering Fig. 6, the cellar pipe is placed in position by seating thecap in the bracket 41 and engaging the hose connection end with thebracket 48 and the yoke end with the bracket 49, the lock plate 52 beingturned to hold the assembly in place. The cellar pipe is removed byswinging the lock plate 52 sidewise whereupon the cellar pipe isimmediately removed from the brackets, and is placed in operativeposition by extending the nozzle tube 2| downwardly through ,an openingin a, floor or the like, and spreading the legs laterally so .as tosupport the cellar pipe onthe two legs and the cellar pipe base. Withthe cellar pipe in the position shown in Fig. 1, the nozzle member maybe moved vertically so as to direct the two nozzles at any desiredangles by vertical movement of the handle, and may be shifted laterallyby swinging the handle and turning the cap in the head I2, whereby anydirectional flow of fluid from the nozzles may be obtained.

It is thus evident that the improved cellar pipe is of simpleconstruction, is readily manufactured and assembled, permits universalflow of the re fighting fluid, is rigid in use, and has no backward,lateral or other reaction thrust, as the flow of a uid through thenozzles is always balanced.
